Single engine night time nosies

[triple8s]

Does anyone remember the thread where someone brought up the scenario where you are single engine night time, maybe over water, and hear imaginary engine roughness? There was a catch word/phrase for it and for the life of me I cant remember what it was called.

"Auto-rough" kicks in everytime I come home from the Carolinas after dark . . . . . Eastern KY and southern WV are dark, crooked and vertical. Then there are the fog tendrils creeping into the valleys . . . . . . When it happened over the Everglades, it was actually Com2 tuned into ATIS with the volume turned way down.

THATS IT! BTW Hank, did you go to the Mooney gathering @ KGKT last year???

Hey, I just went to the Bahamas in my aircraft right before annual and an engine teardown, and did not get the "automatic roughs" one single time.  I was listening for it, but never happened.  Good engine, dependable, I hope the rebuilder doesn't do something to screw it up.

I am just to the west at DKX. I arrived a bit late to the gathering but it was nice to see all the Mooneys there. I sometimes fly up to the north to LOZ because there is a resturant on the field there. The food is pretty good and in the summer you can set out on the patio, I love the eating trips.

I had a PA38 Tomahawk I was taking to Florida and was just crossing the mouth of Mobile Bay going east when I had a particularly noticeable case of auto-rough.  After about another mile over the water it was clear it was not auto-rough, it was the other kind!

I did a Reno-style pylon 180 that would make Lyle Shelton proud and got it to Mobile downtown airport. The bottom plugs in that O-235-L2C were completely full of lead and the top ones were in bad shape too.  Borrowed a socket and a couple wrenches, cleaned the plugs, and good to go.
